Tracking control for a class of uncertain nonlinear switched systems

This paper investigates the controller design problem for output-constrained uncertain nonlinear switched systems. By applying the idea of p-times differentiable unbounded functions and the backstepping technique, a novel method is proposed to design state-feedback controllers such that the system output of a class of uncertain switched nonlinear systems in lower triangular form can track a constant reference signal asymptotically without violation of system constraint.
